If you choose Yes for "Words adjacent," you can type in the phrase
european contract law and the system
will understand that you want only records that have the word european
NEXT to the words contract and law.

Lowercase letters will find matches of capitalized words also. For example, principles will find matches for principles, Principles
and PRINCIPLES.

You may use the Boolean operators AND and OR in your search string. For
example, you could type (globalisation OR mondialisation) AND law to retrieve all
records having globalisation or mondialisation in them, together with the
word law.

Use the ? character to find matches that contain portions
of words. For example, unif? will retrieve unification, unifying,
unificazione, etc. In another example, ?ology will retrieve
technology, typology, etc. The ? character
may also be used to find variant spellings. For example, harmoni?ation
will find both the American spelling, harmonization, and the British
spelling, harmonisation.
